eating?andijmountingaxles in= locomotive I frames to suit the main arid-s de rod centers.

" In the assemblingoflocomotives; slight variations and irregularities inframefdimensions and lot-her crelated. parts make I it extremely dilficult 'toproperlyset and locate. the axles permanently in theframe to properly suit the main and-side rod; CQIIl'EITSMaIld at'the same time have a proper'fitfin the frame'openings; andthe principal object of this invention is to devise a simple *-meth0d;for overcoming this difficulty. r a

Myl invention {consists principally in settingthe rods on: one g side of a locomotive frame on deadcenter, then squaring themain driving i'axle' with the frame and then permanently'fixing both ends of said axle in thls position by suitable means,t hen permanently fix'ingithe remaining-: axles tofplace'gin the frame openings atthei'r ends" at which the side rods :areyo'n "dead center, and finally setting the side rods on the other side 1 of said; frame on dead center andywhilefinf this positionper "manently fixing, the ;;re1naining ends of the v axles. \My'inventionfurtherjconsists in pro v a. v-idinga locomotive frame with axle housing or journal box receiving openings of sufficlent slzeso-as to enable the axlehouslngs or ournal boxes when bein'g assembled in the frame ;:to have aloose fit in saidopenings and beica- 2' I ipable of longitudinalmovement therein for alteration ofthe .loc ation'of said axles] My inventiona-ls'o consists in the method I and in the steps hereinafter? describ'edand claimed.

I Figqg is an, end view, with ,p arts broken away, the wheel removed, of one end of an axle and housing placed in a frame opening showing the means used for altering the -l0- cation and'permanently mounting said axle intheframe;and I I Fig.4tiis'a'plan view of one e nd-iof anaxle 4, with wheels 5 provided thereon, are mount-' ed in housings 6,,ithe' ends of which extend inthe openings 2: In order to providefor extreme flexibility of the truck, cylindrical trunnions 7 protrude from {each side of the axle housings 6 and extend into openings providedin slidable,channel-shaped guides 8 whose flanges, extend'on either side-of the o pedestals/3, and a suitable wear plate; 9 is interposed hetween thelguides and thepedestals. The load is :carried from the wheels totheframe by means-bf fan equalizer 10 (shown in'dotted lines inFig. 3) the ends of which bear'on suitableIseats-provided on the, top of the axle housinggand the center of which support the. springs (not shown) which carry the frame.

In carrying out my method, the openings provided in the locomotive frame for receiving the axle housings are of such asize, that V the length thereof is slightlygreaterthan the combined-length of the axle housings, guides and'wear plates, and thus slight clearance is provided on. both ends of-Qthe 7 opening for allowing slight longitudinal rnovement'of the axleswith respect to thejframe when assemblingthe axlesin the framegc complete axle and wheel assembly isplaced" loosely. in theframe andthe-lside rods 12a and 12?), main. rods l3a and-13b andother related parts are then assembled, and; mounted on the wheels 5g The" rods 12 a.and:13a
